Litvinenko suspect a no-show at UK poisoning inquiry

A Russian wanted in Britain over the death of ex-spy Alexander Litvinenko will not appear before an inquiry into his poisoning, the probe heard on Tuesday.

After several days of uncertainty, Dmitry Kovtun failed to give evidence via video link from Moscow to the inquiry at London's High Court by a 0800 GMT deadline set by its chairman.

Underlining his absence, the video link to Moscow was briefly activated, showing an empty chair.

"That would seem to make the situation crystal clear," Robin Tam, one of the inquiry's lawyers, told the court.

Kovtun and a second Russian, Andrei Lugovoi, are wanted by British police for allegedly poisoning Kremlin critic Litvinenko at London's Millennium Hotel on November 1, 2006 using tea laced with the radioactive isotope polonium-210.

The inquiry is a source of tension in British-Russian relations, along with the conflict in Ukraine, last year's downing of Malaysia Airlines flight MH17 in eastern Ukraine and repeated cases of Russian military aircraft flying close to British airspace.

"This unhappy sequence of events drives me to the conclusion either that Mr Kovtun never in truth intended to give evidence and that this has been a charade," Robert Owen, the judge chairing the inquiry, told the court.

"Alternatively, if he has at some stage been genuine in his expressed intention to give evidence, obstacles have been put in the way of his doing so."

The businessman said he would be committing an offence under Russian law if he testified unless he secured permission from authorities in Moscow.

The inquiry received the first indication late Thursday that Kovtun may not give evidence but gave him time over the weekend to change his mind.

"I will not be able to give testimony today, tomorrow or the day after tomorrow," Kovtun told Russia's Interfax news agency on Monday.
